Put the straws into the bananas
In a bowl, mix the cocoa powder with the melted coconut oil, the agave syrup/coconut blossom sugar (or, if not vegan, also honey). This should create a very tough mass.
Gradually add hot water and stir constantly. Until a creamy, chocolate-like consistency is created. Attention: It should not be too fluid.
Then dip the bananas in the chocolate cream, or spread the chocolate on the 4 banana halves with a spoon. Attach the bananas to a flat plate with clingfilm. If you like, you can top your banana popsicles with nuts, peanut butter, crumble or chopped chocolate.
Then let the banana popsicles freeze for a few hours.
Take them out of the freezer and enjoy!
